Voltage appears at base of transistor and current flows through it. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Current through base of transistor will be zero. The description for each pin is given below.

Output 1Y is connected to LED through a resistor. The LED is connected to know the output status. The LED is connected to know the output status. Because base current is present the transistor will turn ON. Now let us take a single gate of the six and connect it as shown in circuit diagram. TL — Programmable Reference Voltage. In the circuit, When button is not pressed: Input here is 1A which is connected to button.

Current through base of transistor will be zero. Because base current is present the transistor will turn ON.

The gates in this chip provide TTL logic outputs which are a must in some applications. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.

Because base current is zero the transistor will be in OFF state.

As shown in diagram, we have a transistor forming a NOT gate. Datasyeet shown in diagram, we have a transistor forming a NOT gate. The gates in this chip provide TTL logic outputs which are a must in some applications. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.

Daatasheet by admin on 4 April We have six of these gates in 74LS04 chip. Voltage appears at base of transistor and current flows through it. Choose the appropriate package depending on requirement.

When you want TTL outputs. Here are few cases where 74LS04 is used. The chip is basically used where a logic inverter is needed. Under OFF sate the total supply voltage appears across the transistor. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.

The chip is basically used where a logic inverter is needed. When button is pressed: Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be 74ls0n. The series are digital logic integrated circuits.

National Semiconductor

If we draw truth table based on above cases, we will have. We can use one or all six of these gates depending on requirement. The internal connection of gates can be given as below. Choose the appropriate package depending on requirement. TL — Programmable Reference Voltage. Here are few cases where 74LS04 is used. These NOT gates 74ls04nn Inverting function.

The description for each pin is given below. Now let us take a single gate of the six and connect it as shown in circuit diagram. We have six of these gates in 74LS04 chip.

Under OFF sate the total supply voltage appears across the transistor. In the circuit, When button is not pressed:
